Part 1:
The pattern for the first sequence goes by the multiples of 12 and you can show your work by adding 12 to the following number. Example:

12 + 12 = 24
24 + 12 = 36
36 + 12 = 48

and go on...

The pattern for the second is one is that you have to multiply by 2. Example:

3 × 2 = 6
6 × 2 = 12
12 × 2 = 24

Part 2:
You would do the same steps shown above. Add twelve to the following number which is 60. So, 60 + 12 = 72. 

You would also need to multiply 2 and 96 since its the given number. 96 × 2 =192.

Part 3: 
The first sequence is an arithmetic sequence because the number 12 is constantly being added.

The second sequence is a geometric sequence because 2 is constantly being multiplied.

I hope this helps!
